| Detailed Description |
A user with the Add Workstations to Domain privilege is detected. Add Workstations to Domain allow a user to connect previously unknown workstations to a particular domain from a domain controller. This right is meaningful only on domain controllers, and is normally only granted to Domain Administrators. This can be a security risk if other users have this right, since this right gains access to the domain's list of users and global groups.
* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.
